Lakes and Salt Flats in Peru and Bolivia15.8S 69.4W
Between the two is the greenish Lake Poopó, a large yet shallow lake in Bolivia’s Altiplano Mountains. Poopó is linked to Lake Titicaca by the Desaguadero River, from which it receives most of its water.
The water of Lake Poopó is highly saline, although the salt gradient has higher values in the southern reaches due to dilution with freshwater from the Desaguadero River in the north.
A minor outlet also leads to Salar de Uyuni in the far south of the Altiplano, but as the lake lacks any major outlet it is classified as an endorheic basin.
